CLARENCE M. EVELETH, OF PLYMOUTH, NEWV HAMPSHIRE.

WEATHER-STREP- To all whom/ it In/my concern):

Be it known that I, CLARENCE M. EvELE'rrr, a citizenof the United States,residing at Plymouth, in the county of Grafton and State of New Hampshire, have invented a new and useful VVeather-Strip, of which the following is a specification.

This invention relates to weather strips, and is designed for application to the bot toms of doors, so as to effect a weather-tight joint between the door and the floor when the door is closed and to be withdrawn above the bottom of the door when the latter is be ing opened, so as to permit of the door swinging uninterruptedly over a carpet or other floor-covering. I

A further object of the invention is to arrange the device for application to the door in the original manufacture thereof in such a manner as to obviate metallic parts at the edge of the door in order that said edges of the door and the ends of the weather-strip may be planed off to fit the door to any irregularities in the door-frame Without requiring the cutting of any metallic parts of the device. This is a very important feature of the present invention for the reason that one size of trip mechanism may be employed in doors of various sizes, the weatherstrip only being varied in accordance with the width of the door. In this connection it is proposed to have the trip mechanism contained entirely within the door prior to the hanging of the latter, so as to permit planing thereof, as described, and to provide for conveniently projecting the trip member at the hinged edge of the door after it has been properly planed, so as to contact with the door-frame and operate the weather-strip.

WVith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and. particularly point ed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is an elevation of the lower portion of a door having parts broken away to disclose the several parts of the present weatherstrip mounted therein. Fig. 2 is a cross-sectional View on the line 2 2 of Fig. 1. Fig. 3 a detail per- Specification of Letters Patent. Application filed ct e 14, 1904- Serial No. 228.

Fig. 10 is a detail perspective view of the outer end of the preferred form of trip-rod.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

In carrying out door 1 is provided with a longitudinal groove 'or way 2 in the bottom edge thereof and said groove is provided'with an'intermediate upright extension 3 to accommodate the actuating parts of the invention. The weatherstrip 4. is a wooden strip having a length equal to the width of the door and of a thickness not exceeding the depth of the groove, so as to avoid projection of the strip when withdrawn into the groove and against the back thereof. At the middle of the strip and upon the top or back edge thereof there is a metallic plate 5, having at one end an upstanding perforate ear 6, with which is detachably engaged the free hooked end of a spring -arm 7, connected to the door. The spring arm 7 is housed within a bracket or hanger 8, which is of inverted substantially U shape in cross-section and of considerable length, there being a screw or other fastening 9 set through the back of the hanger and into the door to rigidly support the hanger. At the outer end of the bracket or hanger are two cross bars or pins 10 and 11, the outer end portion of the spring-arm 7 being coiled around the pin 1] with its free end engaging the pin 10, thereby to impart an upward tendency to the arm, so as to yieldably maintain the strip Within the groove or way 2, so as to avoid projection of the strip when not required for use.

The means for projecting the strip below the bottom of the door consists of an angular or bell-crank trip-lever 12, which is fulcrumed within the inner end of the bracket or hanger 8, as indicated at 13, with the free end of its long and lower arm working upon the top of the present invention the.

the plate 5 at the middle of the weather-strip. The upstanding arm of this lever is forked or bifurcated, as at 14, and receives a flanged tubular guide member 15, in which slides the inner end of a trip-rod member 16, having its inner end portion smooth and its outer end portion threaded. At the middle of the rod 16 there is a lateral projection or arm 17, which may be conveniently produced by bending or kinking the rod and is intended to engage either side of the extended portion of the groove 2, so as to prevent rotation of the rod. Upon the threaded outer end of the rod 1.6 is an internally-threaded tubular extension 18,- the outer end of which is solid and provided with a transverse perforation 19 and mounted to slide in a tubular guide or sleeve 20, driven into the outer end of an opening 21, which accommodates the trip-rod and intersects the hinged edge of the door. A helical spring 22 embraces the inner end portion of the trip-rod 16 with its outer end connected to the rod in any suitable manneras, for instance, by bearing against a pin 23, carried by the rod, the forward end of the spring bearing against the tubular guide 15.

When the door is open, the spring 7 maintains the strip 4 retracted within the groove in the bottom of the door, whereby the latter may swing freely across the floor into its open and closed positions. It will of course be understood that the present device is fitted to the door prior to hanging the latter upon its hinges, and the trip-rod extension 18 is intro duced into the outer end of the opening 21 and engaged with the trip-rod 16, the portion 18 being conveniently rotated by means of a nail or the like inserted in the opening 19. The outer end of the member 18 is permitted to project a suitable distance at the inner edge of the door. After the door has been hung upon its hinges chalk or the like is applied to the outer end of the trip-rod and the door is then closed and again opened so as to pro duce a mark upon the door-frame where the trip-rod contacts therewith, and a screw 24 is then set into the frame at the chalk-mark, so that the head thereof may take the wear occasioned by the outer end of the trip-rod. It will now be understood that when the door is closed the outer end of the trip-rod contacts with the doorframe, and is thereby shifted longitudinally inward, whereby the spring 22, pressing against the guide 15, operates to rock the lever 12, and thereby project the weatherstrip downwardly below the lower edge of the door into engagement with the floor.

It will here be explained that it is proposed to manufacture doors with the present weather strip arrangement therein, said doors being placed upon the market with the sleeve or ferrule 20 and the tubular rod member 18 detached from the door, in order that there may be no metallic parts at the edge of the door to interfere with the planing of said edge and the adjacent end of the Weather-strip to fit the door to irregularities in a door-frame, the

ferrule and the tubular rod-section being applied after the door has been properly planed.

While the form of the device thus described is effective for the purpose designed, it has the disadvantage that the ferrule 20 and the tubular rod-section 18 must be shipped detached in order that the edge of the door may be planed to fit a door-frame, and to overcome this difliculty I have provideda preferred construction (shown in Figs. 8 and 9 of the drawings) wherein the push-rod 25 is a single piece and is threaded and engaged with a pair of nuts 26 and 27, which have a slidable fit within the groove or recess in the bottom of the door, but are non-rotatable therein by reason of their sides engaging the sides of the recess. That portion of the rod which lies between the nuts is slidably re ceived in the sleeve 15, which fits in the lever 12, as hereinbefore described, there being a helical spring 28 embracing the rod and bearing in opposite directions against the sleeve 15 and the nut 26. With this form of triprod when the door is shipped from the factory the rod is screwed through the nuts 26 and 27 until its outer end is entirely within the door, whereby the edge of the latter is free from metal parts and may be readily planed. After the door has been planed the rod may be turned upon its threaded connection with the nut, so as to feed the rod out wardly to project it beyond the door into position for engagement with the door-frame. To facilitate these adjustments of the rod, a screw-driver groove or seat 29 is formed in the outer end thereof.

Having fully described the invention, what is claimed is- 1. A door having a weather-strip working in a slot in the bottom of the door, means housed within the back of the slot for projecting the weather-strip and including a trip-rod working through the hinge edge of the door for contact with the door-frame to project the weather-strip, said rod capable of being shifted in an endwise direction to bring its outer end within the hinge edge of the door, whereby said edge of the door may be planed without interference by the rod.

2. A door having a weather-strip working in a slot in the bottom of the door, and means housed within the back of the slot for pro jecting the weather-strip and including a trip-rod working through the hinge edge of the door for contact with the door-frame to project the weather-strip, said rod having a threaded adjustment for moving the same endwise to a position entirely within the door, whereby the hinge edge of the door may be planed without interference by the trip-rod.

3. The combination with a door having a slot in the lower edge thereof with the intermediate portion of the slot extended to form a recess, the door being provided with an opening intersecting its hinged edge and the recess, a Weather-strip Working in the slot, a spring to yieldably retract the strip, an anglelever fulcrumed Within the recess with one end portion engaging the strip, an endwisemovable threaded trip-rod working through the opening in the door and also through the opening in the lever, non-rotatable slidable nuts Within the recess at opposite sides of the lever and adjustably receiving the threaded portion of the rod, and a helical spring embracing the rod and bearing against the lever and the outer nut, the outer end of the rod 15 bein provided with a screw driver seat whic is accessible through the outer end of the opening in the door to permit endwise adjustment of the rod.

In testimony that I claim the foregoing as 20 my oWn I have hereto afliXed my signature in the presence of tWo Witnesses.
